Jennifer says being on Oprah's stage feels pretty good! "The Grammys were a good moment definitely—where you just go, 'How is this even my life, really?'" she says.

"When you're little and you're growing up, and you're hoping, you're wishing and you're dreaming to think that it can actually happen...," she says. "This is stuff that dreams are made of, and we are doing that. We are living that."
